A user equipment (UE) may initiate a direct inter-device communication link between UEs located in proximity. The UEs participating in the inter-device communications may perform a device handshake procedure or a device discovery procedure to set up appropriate transmission parameters for the communication over the inter-device communication link. A device-to-device radio network temporary identification (DD-RNTI) may be used for the inter-device communication link. Long term evolution (LTE) downlink or uplink radio resources may be used for communications over the inter-device communication link."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device handshake/discovery for inter-device communication in wireless communication systems","description":"Systems, methods, and apparatuses for inter-device communication in wireless communication systems are provided.
